I'm not so sure about rules causing chaos. It's true that undisciplined children will act out their bad feelings in any situation where they're not in control, thus creating chaos in response to rules they don't appreciate. However, we'd expect 3D users and artists to be able to exercise more self-control, even if the age limit here is only 13 or whatever. But I do agree on the part about the merchants producing images that advertise their items - I say they should allow it. After all, if it's okay to dump dozens of ads for the latest Daz figure in the Poser forum every week, why not give the merchants a little more free rein?
